Since 2008 firmware came out, I've been having problems with my memory cards (sandisk 2gb). I have no desktop/laptop, only my tablet, but I had tested the cards in my camera. Formatted them with the camera and filled them up w/ video. Cards worked great. Upon returning the cards to the n800 they began showing problems again. I was unable to create virttual memory, and could only copy a smalll amount of data to them before getting a connection error. Yesterday got ahold of a PC.... no card reader but formatted both cards via USB. Still had same problems.

Today, on a hunch, I tried something different. Before, after formatting in camera or via PC, I always reformatted again with format tool in n800 file manager. It would seem to be at this point where the cards became corrupted. Today, after formatting via PC/usb, I attempted to create virtual drive without running a 2nd n800-based format ... and for the first time since upgrading to 2008 I was able to create the swap file. I am also now able to copy large numbers of mp3 files to cards.

I can only conclude from this that the n800/2008 format tool is somehow broken.

Can anyone confirm this behavior? At some point I will reformat internal card again with format tool and see if it 'breaks' the now working card.... but can't do this until I'm certain I'll have access to a PC to fix again if neccessary.

Note: 125mb card did not have problems.. only the larger sized cards.

I dont know about format tool. But N800 external memorycard did corrupt last night first time. I am using latert official OS2008 and one of my MP3 folders was total mess. I did format with filemanager and copy files back to memorycard. I dont have cardreader that support SDHC cards and it was really slow with USB cable.

follow-up:

I removed the virtual memory and rebooted. I then opened file manager and reformatted the card. I then tried to create a new virual memory space... no luck. Card is corrupted again. I'm surprised no one else has reported problems; I wonder if reflashing could fix :/

When I went too reformat via pc I noticed that the nokia file manager had forrmatted the now broken card fat32 .... When formatting via winndows I had been selecting fat, which works.

Can anyone who understands such things comment? Does fat32 mess up the cards? If so, why does the built in format tool use it?

Download the above low level formatter. Thanks to fanoush!

Hello,
I just entered in SD broken Club... I had an A-Data sdhc 8 gb memory card...worked ok for 3 weeks in internal slot, but for last 2 days n800 said something about corrupted or unformatted card. I tried to format it on my laptop and it worked, except that n800 gave same error.
I just formated it with file manager formatter and surprise... IT WORKS..
except that now has an amazing capacity of 484 kb (yes... less than a mb)

Also I tried with the formatter from panansonic, but didn't worked, neither now, nor before formatting on n800.
I tried to format it again on laptop, but it seems to format it at the same size.

Any suggestion?

last night i copied my data with File Manager from a 256mb mmc to tthe fat32 partition of a 16gb sdhc (formatted with gparted on my pc with 1 huge fat32 partition, a 512mb ext2, and a 512mb swap), which worked fine when i accesed on both n800 and pc. then i selected "extend virtual memory" in the memory control panel. suddenly file manager only sees less than 500mb of the card. when i plug it into the pc, the partitions are still there, but their names are gone, the big partition is empty, and the ext2 partiition just shows a 27.8mb lost+found file.
so, did i do something wrong, or is something fishy happening?
i'm running the latest os2008 on an n800. i have had an 8gb sdhc card in the external slot, working fine since the october release of os2007 (with only 1 fat32 partition), with a 256MB mmc card in the internal.
